over burlap, runs a line of stitching along and through the folded overmargins and then along and through the unfolded over selvage margins ofwhat later becomes the bottom of the bag. The bag is then turned insideout and is ready for use as a new bag with the seams on the inside ofthe bag. I When such new bags are to' bear the brand and trade marks ofthe purchaser, they are run through a bag printing machine. After theoriginal use of such a new bag, in many instances,

the bag is t for reuse while others must be re' conditioned and arereturned to the market asreconditioned bags.

To recondition a bag, several operations are necessary and among themare the thorough cleaning of the same and the patching and darning ofthe Worn spots and holes. Again, it is notA desired that the originalbrand marks be displayed in a reconditioned bag and therefore to concealthe same, the bags are returned inside out and preferably this is doneduring the cleaning operations so that the brand marks are on the insideof the bag.

Burlap is a loosely woven jute fabric often referred to as gunny and hasrelatively heavy warp and weft threads that easily ravel and fray andslough off as lint at the edges so that such edges are rough and ragged.After the bag has vthus been returned inside out, it is apparent thatthat side of the bag having the turned over margins presents quite anunsightly ravelled and frayed appearance and theselvage edges below theline of stitching present an uneven and wrinkled appearance whichdetracts from the salability of the bag as a used bag.

The primary object of the inventionA is to provide a reconditioned bagwhich is much stronger at its stitched edges than is a new bag and whichhas a, neat and attractive bound edge free from ravellings or frayings.

Another object of the invention is to provide a novel side seamv for a.reconditioned burlap bag which may be more readily produced by sewingmachine operation having a simple Vfolder and at the same time presentsthe entire seam to the view of the operator for a better control of theproduction of the seam, at high speeds.

The above mentioned objects of the invention, as well as others,together with the many advantages thereof, will more fully appear as Iproceed with my specification.

In the drawing:

Fig. l is a perspective View of a burlap bag turned inside out, readyfor making the side seam thereof into one embodying the preferred formof the invention.

Fig. 2 is a perspectivevview'of a burlap bag having the improved reboundside seam therein.

Fig. 3 is a sectional view on an enlarged scale, through the side seamof the bag appearing in Fig. 1, along the line 3 3.

Fig. 4 is a transverse sectional detail perspective view through theside seam of a bag Referring now indetail to that embodiment of theinvention illustrated in the accompanying drawing: 5 indicates as awhole a used burlap bag which comprises the two side walls 6-6 joinedtogether at one side and the bottom to leave the bag open at the top asin the usual manner. Such a bag as originally made, is produced from alength of burlap having top and bottom selvage margins 1 1, cut from astrip of such burlap and then folded at the middle into two superposedlayers that form the bag walls in a nished bag. Before such a foldedlength of burlap is stitched along one side and the bottom, the freemargin of each layer or wall is folded outwardly and back upon theassociated layer and such margins are indicated at 8 in Fig. 3.Thereafter the bag is stitched as at 9, beginning at one corner thereofand following down and along the folded over margins 8 4, around thecorner I0 and along the bottom of the bag.

The line of stitching 9, which will be hereinafter referred to as theoriginal line of stitching, passes through four thicknesses of bagmaterial at the side of the bag and passes through two thicknesses ofbag material at the bottom of the bag. In laying in this line ofstitching, it is attempted to place the same in the median line of themargins 8 and as the bottom end of the bag is approached, said linetakes a curved path and passes into the bottom, thereafter substantiallyparalieling the line of the selvages 1. After the ybag has thus beencompleted, it is turned inside out to position those portions beyondsaid line of stitching inside the bag.

Atfer the bag has been used, and in reseaming the same in accordancewith my invention, the bag is re-turned inside out so that it is in thecondition shown in Fig. 1.

' and folded side edge of the bag is relatively free from the sidewalls. These free marginal portions II are usually frayed and dened byend parts of the warp threads of the bag fabric as the weft threadsslough oif therefrom.

Beginning at the open top end of the seamed side of the bag, both foldedover margins 8-8 are refolded over inwardly and then back down upon onewall 6 of the bag. In this refolding over of both margins as mentioned,the free portions II of both margins are folded back upon the otherportions o f their own margins 8 and thus cover up both sides of theoriginal line of stitching 9, as shown in Fig. 4. The refolding of themargins 8--8 back upon the same side wall of the bag can be carried outon a sewing machine having a folder and capable of producing an overcaststitch I2. f course, the line of overcast stitching I2 follows closelyupon the rolling or refolding of the margins 8 and the straight stitchesI8 thereof pass through only the two walls 6 of the bag while the loopstitches Il pass about the rolled portions to hold the same in place asbest shown in Fig. 4.

It is apparent from the above that a transition in the seam structureoccurs at the corner I0 of the bag because that portion of the same,along overcast stitching mentioned is made continuous and extends fromone top corner of the bag down the seamed side, around the bottom cornerof the bag and then across the bottom of the bag to terminate at thatbottom corner diagonally opposite the first mentioned corner. Also thatfrayings and ravellings of that free portion I I of the exposed margin 8along the side of the bag are turned back upon the other portion of itsmargin and are bound in place by the loop stitches I4.

The bag is thereby reenforced and strengthened at its side seam whichenhances its appearance and makes it more salable as a reconditioned bagand which meets the demand vfor a good strong burlap bag, tight at itsseams and ready for long periods of reuse:`

As'both margins are turned or are refolded back upon one side 'of thebag and which side is the upper or top side when the bag is being fedacross the bed plate of a sewing machine, the said margins are in fullview of the operator so that the bag may be more readily guided throughthe stitching operation to provide a more uniform and straighterfinished bound seam.

While in describing the invention, I have referred in detail to theform, arrangement and .construction of the several parts thereof, Le

same is t0 be considered merely by way of illus- `tration so that I donot wish to be limited thereto except as may be specifically set forthin the lappended claims.

I claim as my invention:

A bag having side walls. a marginal part of each of which is foldedback upon one side of an associated side wall, both of said folded overmargins being refolded back upon one of the side walls of the bag, andstitching securing said side walls togethervas well as securing saidrefolded margins together and to said side walls.
